1 1 A li ti filed December To'all whom it may concern:

Be it known that I, ARTHUR W. SMITH, a citizeniof the United States, and resident of the boroughof Manhattan, city of New. York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of

which the following is a specification.

My invention relates to typewriting ma chines of the-type bar class and has for its main object to provide-improved constructions of type bars and type bar hangers for such mac 'nes.

1 Another bject of theinvention is to pro- I uniform ,type'bars, each t being confined within arelativelysmall space .orarc.

,vide aset of type bars and hangers for a visible writing machine-in which the type bars have exceptionally wide bearings.

A further object is to provide a series of e bar having unusually w1de,bearings an the series of bars To the above and othernds the invention consists in the featuresfiof construction, arrangements of parts and combinaiions of devices hereinafter fully described and par tioularly pointedout in the claims lathe accompanying drawings, Figure-1 i is an enlarged fragmentary front view, partly insection,showi ng a type bar support and a plurality of type bars mounted thereon, one of said type bars being shown in printing position against the platen. Fig. 2 1s a side view, partly in section, of one of the t e Fig. '4 is a fragmentary perspective -view I the pivotal axes of the type bars and viewbeing on a still larger scale than Fig. 2.-

Although I have shown my invention as applied to 'a series of type bars arranged for cooperating with the front face of a platen which is arranged above the segmental support upon which the type bars are mounted and which arrangement corresponds to that T of'machines commonly known as front-strike typewriting machines, nevertheless-I desire it'to be understood that my invention is not limited tosuch an arrangement but maybe' speciflcatimifihtters Patent.

adapted to other kinds or styles of writing machines. The drawings illustrate a platen 1 below which is vertically arranged a segmental type bar support 2 formed with aslot 3. Mounted on the segment 2 are type bar hangers 4, each of which, as best seen in Fig. 3, comprises a shank 5, a base 6 and a bearing por tion 7, the latter being bored out to form a bearing eye 8? The shank 5 is provided with a threaded opening 9 and is received in the slot 3 in the segment. A washer 10 (Fig. 2) bridges the slot behind each hanger 4 and is formed with a hole which permits the passage of a securing screw 11 which takes into the threaded opening 9 in the hanger and secures the latter in place on the segment .with the'base 6 abutting the front face of said segment above and below the slotted opening 3.

Cooperating with each han er 4 is a type -bai 112, each type .bar preferably comprising 8. '0 a'lthoiig if desired, the type bars may be .made in one iece. The rear or piv'otal end ofeach t pe bar is bored out to form an eye 13' whic jreceives the pivotal portion 140i the type'bar, said pivotal portion being preferab'ly in the form of a hollow cone-like part which extends transversely of the body portion of the type bar and projects laterally from either side thereof. The apex of the cone is capped by a rounded-,spherical or bail like bearing end 15 which is at some distance from one side of the body of the bar,

bearing portion 14 is formed-at" its top with a cup-like journal or bearing 17, best shown in Fig. 5. The baseofthe cone-like part 14 terminates in a hollow cylindrical flange 18 which forms af shdulde'r"19 with the outer surface ofthe cone-like portion of the part 14, which shoulder abuts against the face of th'ehody ortion surrounding the eye 13 at the opposite side ofthe bar from the ball-like bearing end 15. When the type bar is made of two parts which, as stated, is the preferred construction, the said two parts 13 and 14 may be secured together in any suitable manner as by soldering.

The series of type bars is preferably divided into two sets one at each side of the center of the segmental support 2 and the con'e-li'ke bearing parts of the type bars of each set are nested one within the other, the

and the cone-shaped opening 16 within the.

rtion 13 anda pivotal portion 14,

ball-like bear ng end 15 of "one type bar of the set being received within the bearing'cu'p 17 of the ad acent type bar in which the first type bar is nested, while the ball-like end 15 5 of the type bar adjacent to the other side of thefirst type bar, and which nests within the first type bar, is received-in the beari cup 17 of the latter. This arra ement wi best be understood froma consi eration of l0 5,. It will be further seen from an examination of said figure that the cylindrical bearing portion 18 of each type bar bears in the bearing eye 8 in the hanger 4 associated with said type bar, so that each type bar has two bearin s spaced apart,- one at each side, one

bearing cup 1*) formed in the of sai bearings being in a hanger and the other in an adjacent type .bar. It will also be seen that each pivotal part 14 is support;

ed at its ends, and that the ball 15 of the- 20 next type bar is pivoted to said pivotal part baris interposed between its own hanger eye and the hanger eye of an adjoining type bar. It ls to beunderstood that while I have shown the part 14 as a complete hollow cone,

my invention is not limited to the precise form shown,- and that the term cone or cone-like comprehends any equivalent;

construction which enables two oppositely disposed bearings, as 15 and 17, to. be offset from the body of the bar and so that the type 40 bars ma be nested as described. It is also to be nderstood that although I have shown and described the base o'f the part 14 as cylindricalfl yet I do not desire to be limited to this precise vshape. The term cylindrical is to be understood as comprehending any shape which is circular in. cross-section and the center whereof lies in the pivotal axis of the type bar, said cross section being at right angles to said axis.

The center of the ball-like end 15 of each type b ar of the set lies in the axis of the conelike p rt .14 within which said end15 is container so that the type bar of which said.

ball-like end 'is apart will not be disturbed when the type bar in. which it bears is given rotary motion; or in ,other words, one type bar is pivotedon another at the point of intersection of the pivotal axes of the two type bars. Because ofthis. necessary arrangement the bearing parts 14 of'the type bars of eachset are all disposed at an les on the segment 2 such that planes indicated by a in Fig. 1), passing through-the rear of the body portions of the bars and erpendicular to the pivotal agree of said ars will an be tangent to a' circle b (Fi 1 lying;

in the perpendicular plane passe through the printing line and having its center at on near the printing point. Consequently the body portion of each type bar forward o f the pivotal end will be bent or off-set as indi cated at 20 (Fig. 1) soas to bring the types 21 on the ends of the type bars into pos tion.

point on the platen when the respective type ars are actuated to print. The type bars are connected at 22 (Fi 2)".byfa part- 23 with any suitable form :of type bar-actuating mechanism. r

The two sets of type bars-comprising the series are oppositelydisposed from the center of the segment outwardly towards the sides thereon and the innermost type bars of the two sets may be maintained prorperly spacedanart by any one f avariety of means. n the present in tance, I have s own a double-ended bearing member 24 .to .properly cooperate with the printing ig. 5), said bearing member terminating in ball-like bearing ends 25 which bear in the bearing cups 517 of the inner type bars; esting and bearing on the first or inmost ty e bar of each setis a second. type bar, -a thlrd bearing on the second, and so on'outvwardly to the last type bar of each set. -As

best seen in Fig. l the bearing end 15 of the last or outermost type barof each set 'is seated in a bearing cup or opening 26 formed in the. inner end of a'screw-like end bearingmember 27 which is threaded ez'gteriorly and engages in a threaded opening in anear 28 fixed to or integralwith the segment 2, one

of said ears being near each end of. the segment. The bearin member 27 is provided with a check or locidng nut 29. By screw-- ing the end member 27 in or out, pressure upon each bearing end 15 of the bars of the associate set maybe decreased or increased,

this pressure being in some degree transmitted to the type bars of the oppositeset through the bear-in member '24. It will, therefore, be unders oo'd that by one or two adjustments the bearing ends of all of the type bars may be'properly adjusted when the partsare assembled and that said hear ing ends may be properly maintained in adjustment in -a similar manner.

I .It will be seen that by the construction and arrangement above described I- am enabled to provide a setvof typebars, the body portions of which he very close together, but

which have, at ,the same time, wide bearings;-

at a donsiderable distance laterally from the sides of the bars, thereby greatly .conducing to the stability of, the latter.

It will further be seen that by my novel arrangements I provide type bars which serve as journals or bearings for other type bars atone time (that is, when said other type bars are actnatedhandyvhich also turn in said other type bars at another time. An

j l'ddltlonaliadvantage of my novel arrangerrie rit is that type bars are nested or housed ;iI1I,8.djOiD iI1g,typ6 bars, thereby having their bea ings protected from dust, grit and fallparticles, I arious changes may be made in the constructionf and arrangement of the parts fyvithout departing from the scope of 'my ina-ifntion, ,NVhatI- claim as newand desire to secure byLetters Pate'nt, is: 7 f,1; A;type bar having a. hollow cone-like I bearing. portion projecting laterally from its gsidefnear its pivotal end and constructed to iagenter and also'to receive similar. cone-like bearings ori'conti uous type bars.
